There is significant variation in hairiness among individuals and populations due to genetics and hormones, but some general patterns have been observed in studies. Caucasians generally have the highest hair density on their scalps and more body hair than other major ethnic groups, while people of Hispanic and Middle Eastern descent also tend to be very hairy.
Each ethnicity exhibits specific characteristics. Caucasians tend to have the greatest number of hair follicles. African-Americans tend to have the fewest hair follicles but have thicker hair strands. West Asians have thicker hairs with fewer follicles, and those from East Asia have thinner hair with more follicles.
“The ethnicity with the least amount of terminal hair is Asian, whereas people of Hispanic and Middle Eastern descent typically have the most. Other ethnicities fall somewhere in between. So what's normal, hair-wise, for you might not be normal for someone of a different ethnic background.”
Anthropologist Joseph Deniker said in 1901 that the very hirsute peoples are the Ainus, Uyghurs, Iranians, Aboriginal Australians (Arnhem Land being less hairy), Toda, Dravidians and Melanesians, while the most glabrous peoples are the Indigenous Americans, Bushmen, and East Asians, who include Chinese, Koreans, ...
Yes, Caucasians (Indo-European and Semite populations) are the hairiest ethnic group. The cause is still unknown. It has been posited that the various Caucasian populations originated in Northern regions at the end of the last ice age.
Japan: Women in Japan have preferred to shave only their legs and underarms, leaving the bikini and pubic area untouched. It is also quite common to remove facial hair and peach fuzz for a smooth, glass-like appearance.
Asian hair is the thickest, with a larger diameter of about 70 µm. Caucasian hair has an average diameter of 65 µm, and African hair is the finest, with a diameter of 55 µm. The cross-section of Asian hair is the most round and uniform, Caucasian hair has an elliptical shape, and African hair has a flattened shape.
Hair growth rates also vary between hair races. Caucasian hair grows at a rate of about 1.2cm a month and has the greatest density of all three hair types. Blondes have about 146,000 hairs on their heads, black-haired beauties about 110,000 hairs, brunettes 100,000 hairs and redheads roughly 86,000 hairs.
The leading countries are Spain with 44.50%, Italy with 44.37% and France with 44.25%. In general, Western countries occupy a significant part of the list of countries with a high percentage of baldness. However, this phenomenon is not limited to the West.
Men develop more androgenic hair than women because we have more androgens. Androgens (sometimes referred to as male sex hormones because we more of them than women) are sexual hormones such as testosterone, androstenedione and DHT, which create male characteristics. This, of course, includes being hairier.
After Caucasians, people of Afro-Caribbean heritage tended to experience the next highest levels of hair loss, with Asian men having the lowest hair loss rates.
Asian hair
Because of its extra diameter, it is also the strongest, and most resistant to damage.
There is no specific ethnicity that can't grow facial hair, but East Asian individuals, such as Japanese and Chinese, tend to have less facial hair and slower growth rates compared to other ethnicities.
Depending on your race, the average age for first signs of graying is the mid-30s for Caucasians, late-30s for those of Asian descent, and mid-40s for African Americans. It is believed that the overall average age when human hair starts to turn gray equates to a person's early 40s.
Japan, Spain and Sweden are widely known for having people with healthy hair, but there are also other countries like India, France and Russia that are also known for helping people keep their hair natural and not messing with any artificial coloring.
Men have higher levels of androgens than women, so their body hair tends to be more prolific. While it's hormones that stimulate facial hair growth, genetics determine how thick and dark a man's facial hair will be, so a fine goatee may be seen as something of an ancestral asset.
Hair Loss by Country
Our study found that Western countries like Spain, Italy, France, the United States, and Germany have some of the highest percentages of bald men. Some other countries in regions such as Asia and South America also show high rates of baldness.
Japan has the highest baldness rate in Asia, with nearly 25% of men experiencing some degree of hair loss. It is not uncommon to see balding men in public or on television, and there is a well-developed hair loss treatment industry that serves them. Recently, attitudes in Japan towards baldness have been changing.
Gen Z is experiencing faster hair loss due to a potent mix of chronic stress, poor modern diets lacking key nutrients, environmental pollution, intense digital lifestyles affecting sleep, and the acceleration of underlying genetic predispositions like androgenetic alopecia (male pattern baldness) by these external factors, all contributing to earlier and more significant thinning. While genetics remain primary, lifestyle stressors are intensifying the issue, causing hair follicles to weaken and shed prematurely.
Skin barrier function is reportedly stronger in darker skin tones (the stratum corneum is the skin barrier). Asian skin is reported to have similarities with Caucasian skin in terms of water loss and has the weakest barrier function.
Immune status has been associated with race, with blacks having higher levels of immunoglobulin A and CD8 cell counts than whites. Furthermore, several studies observed that whites and blacks living in the same geographical region had different levels of γ-globulin, a marker of immune disruption.
Thick hair was reported in 40.7% of African ethnicity and 26.3% of Asian ethnicity. Thin hair was reported in 34.7% of European ethnicity and 23.3% of Asian ethnicity. Dry hair was found in 46.7% of African, 33.2% of European, 35.8% of Hispanic, and 35.1% of Asian ethnicity.
Genetics (which controls ethnicity) is the number one cause of hair loss. Certain races have higher rates of hair loss compared to others. Caucasians have the highest rates out of all the ethnic groups. On the opposite end of the spectrum, Native American Indians, Inuits, and Chinese have the lowest rates.
Understanding these ethnic differences helps explain disparities in hair length and health across populations. Asian Hair: Fastest growth rate: averages 0.55 inches/month (13.9 mm).
Varieties of black hair
Appearing as being almost blue in some conditions, this hair color is mostly found with people from Africa, South and Southeast Asia, East Asia, Central Asia and Latin America. True black hair is similar to a black cat's fur.
